Tourette disorder in North Dakota.

This paper describes the symptom profiles of a large group of patients with Gilles de la Tourette disorder (TD). In Part one we report the results of a questionnaire study of patients in North Dakota with TD. The data suggest that TD patients have high rates of academic and social problems. Obsessive-compulsive symptomatology is quite high in this population. This report is unique in that these results are reported using an available data base to allow for pooling of future research in TD patients in other settings. In Part two of this paper we discuss important findings from our clinic population of 130 TD patients.
